En Croissant is an open-source, cross-platform chess GUI that aims to be powerful, customizable and easy to use.
I've been working on a fully-featured chess GUI that has all the nice features of Lichess, Chess.com and Chessbase combined into a single app. There's still a lot to be done, but it already covers a big range of things you might want from a chess analysis app.
Here's some of the features available:
Analyze with multiple local and cloud engines at the same time
Game report with evals and annotations (ranging from blunder to brilliancy)
Single-click engine and database installations
Advanced database search options like searching for games with similar pawn structures
Download games from chess.com and lichess accounts
Get stats from openings you've played and see ratings over time
Store and manage PGN files (like lichess studies) locally
Practice positions from your opening files and keep track of your learning progress
Offline tactics training (with the full lichess collection of 3 million puzzles)
